Briefings

Scientists at the Harbin Institute of Technology and the Chinese Academy of Sciences have developed an experimental cement-based supercapacitor that could power emergency lighting, fire alarms, and sensors within buildings using the building's own structural material. This technology aims to eliminate the need for external fuel sources or bulky battery packs, offering a sustainable energy storage solution for infrastructure. The research was published in October 2026 by the American Chemical Society and highlighted by the Chinese Academy of Sciences.

Key points

• An experimental cement-based supercapacitor has been developed by researchers at the Harbin Institute of Technology and the Chinese Academy of Sciences to power building systems like emergency lighting and sensors.
• The device utilizes the building's existing structural material as the energy storage medium, eliminating the need for external fuel sources or bulky battery packs.

Context and limitations

This research is currently limited to experimental cement-based supercapacitors; no commercial applications or performance data are available.
